Comparative study of type 2 median crossovers and median u-turns
(University of Missouri--Columbia, 2008)
Many states use rural expressway median crossovers which provide for separation between the two opposing traffic lanes to manage the direct left turn movements between the expressways and cross roads. As the volume increases on the major road...
An in depth evaluation of internal criteria for determining the number of clusters in a data set
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Clustering procedures partition data sets into groups, minimizing the distance within clusters while maximizing the distance between clusters. Clustering can be a powerful tool...
Associations between psychosis risk and emotional distress disorders with cortical surface morphometry
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI-COLUMBIA AT REQUEST OF AUTHOR.] Neuroimaging studies have consistently found structural cortical abnormalities in schizophrenia, especially in structural hubs. However, it is unclear what...
Numerical solutions to the Poisson equation in media surrounding multiple arbitrarily shaped bodies
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The dissertation describes a general, efficient, and parallelized approach to solving the Poisson equation in the volume surrounding multiple, arbitrarily shaped bodies. Green...
Photoacoustic detection of circulating tumor cells
(University of Missouri--Columbia, 2013)
based on the change in refractive index was developed to detect individual melanoma cells. The sensitivity of the optical based detector was high and has the resolution to determine the presence of extremely low number of metastatic and cultured cells (2...
Modeling the financial impact of management decisions on loblolly pine (Pinus taeda) production
(University of Missouri--Columbia, 2010)
Located primarily in the southeastern United States, Loblolly pine (Pinus taeda L.) is a variety of Southern yellow pine that is often planted by non-industrial private landowners seeking a beneficial long-term investment ...
Stand structure development effects on wood quality of Melina (Gmelina arborea roxb.)
(University of Missouri--Columbia, 2009)
of log grade through the harvest cycle shows the highest increments at Cordoba region. Dendrometric variables such as heartwood, sapwood, and diameter and crown height are good estimators of tree volume, taper and branch modeling....
Watershed-level Analysis of Urban Raingarden Performance
(2013)
Urban flooding became to be a big issue for many cities in the world due to the urbanization. Best Management Practices (BMP) are considered to be an economically friendly solution for the urban storm water problem.
The ...
Generation, collection and characterization of nanoparticles and their diffusion in arbitrary tumor and normal tissue geometry
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Nanoparticles have unique electronic, optical, mechanical, magnetic and chemical properties that are significantly different from those of the bulk materials. Because of this...
Statistical and simulation methods for evaluating stationary and mobile work zone impacts
(University of Missouri--Columbia, 2018)
when traffic volumes are under 1400 veh/hr/ln, and preferably under 1000 veh/hr/ln, due to the drastic increase in the number of conflicts. In addition, three data driven models were developed to predict traffic speed inside a MWZ: a linear regression...
A genetic approach to determine river otter abundance in Missouri
(University of Missouri--Columbia, 2010)
's effects on sport fish populations have sparked controversy. The MDC responded by increasing efforts to monitor river otter populations, using latrine site counts to measure relative abundance across several rivers in Missouri. However, the actual number...
Designing a LANDIS PRO harvest module and examining the effects of temporal resolution on simulation outcomes
(University of Missouri--Columbia, 2012)
and testing of a disturbance module that simulates harvest events in the LANDIS PRO model. The design operates on quantitative attributes such as number of trees and basal area to control harvest events, giving the user the ability to parameterize harvest...
Nectar in nicotiana : pollinator associations, sources of variation, and evolutionary consequences
(University of Missouri--Columbia, 2007)
significant heritable component was detected for nectar volume and energy, as well as corolla tube length, in an experimental population of Nicotiana alata. Although phenotypic correlations were significant for all measured traits, only two correlations had a...
Economic analysis of woody biomass harvesting in the Missouri Ozarks
(University of Missouri--Columbia, 2010)
An integrated mechanized timber harvest thinning treatment to remove small diameter trees and merchantable saw logs was conducted on 30 acres of the Missouri, Ozarks in the summer of 2009. Two silvicultural treatments (single tree selection...
The effect of environment on seed composition of tofu and natto soybean cultivars
(University of Missouri--Columbia, 2006)
Composition of soybean seeds is important to manufacturers of tofu and natto food products. The effect of environment on seed composition of tofu and natto soybean cultivars was measured in Missouri in 2004 and 2005. The environment was altered...
Rheological and morphological evolution of basaltic lava flows
(University of Missouri--Columbia, 2018)
question of how pre-existing topography controls lava flow system structure in volume-limited flows (Soldati et al., accepted). I concluded that a steep slope results in a single, stable channel, whereas a gentle slope results in an unstable, braided...
Impacts of Precipitation, Land use Land cover and Soil type on the Water Balance of Lake Chad Basin
(2013)
Lake Chad Basin (LCB) has experienced drastic changes in land cover and poor water management practices during the last 50 years. The successive droughts in the 1970s and 1980s resulted in a decrease in surface water and ...
